Jamie-Lynn Sigler and her fiancé Cutter Dykstra introduced their new baby, Beau, on Instagram.

Jamie-Lynn Sigler, who played Meadow Soprano, Tony Soprano's daughter on the HBO series "The Sopranos," and her baseball-player fiancé Cutter Dykstra welcomed their baby boy Beau Kyle back in August.

But Jamie-Lynn Sigler and Cutter Dykstra didn't automatically thrust young Beau into the social media stratum. Last month Jamie-Lynn Sigler posted a photo of Beau's hand to Instagram.

Jamie Lynn Sigler and Cutter Dykstra shared their first public photos of Beau in the latest issue of US Weekly. She said "I get how they say you will never know what love is until you have a child. It's such an overwhelming feeling of responsibility, of love, of fear, of everything."

According to US Weekly Jamie-Lynn Sigler endured 36 hours of labor before Beau Kyle was born on Aug. 28 at 3:53pm in Los Angeles at 8 pounds and 4 ounces.

Sigler took to Twitter to announce the US Weekly interview and share Beau Kyle's first public pictures
